Abstract

Mutation breeding in crop plants such as brinjal (Solanum
melongena L.) is a successful approach in change of product
having narrow genetic base and to explore it a field experiment
was conducted toevaluate the effect of physical mutagen
such as gamma rays and chemical mutagens such as Ethyl
methane sulphonate (EMS) were used on two brinjal
genotypes namely Banarasi Gol and Kashi Taru. The seeds
were treated with different concentrations of gamma
irradiation (5, 10, 15 and 20 kR) and EMS (0.05, 0.10, 0.15 and
0.20%).The increasing concentration of mutagens was
recorded with a negative response on all growth and yield
attributes of both the genotypes which ultimately reduce
the yield. In this context the 5kR gamma rays and 0.05%
EMS concentration were recorded with superior values of
all characters in M2 generation. Early flowering and early
edible fruit maturity was observed under 5kR gamma rays
over all other treatments. The fruit yield per plant increased
by 19.87% and 20.30% of Banarasi Gol and Kashi Taru,
respectively under 5kR gamma rays over control. Lowest
value of all characters was recorded under 0.20% EMS as
compared to all other treatments including control. Thus it
can be concluded on present study basis that the increasing
concentration of mutagens were showed an adverse effect
for all characters.
